The main purpose of the Instagram algorithm is to make each user's experience with the platform as pleasant as possible. Instagram CEO Adam Mosseri refers to the algorithm as “ranking” (maybe because that term sounds less robotic) and stresses the importance of favoring some posts more than others.

📣 Announcing some changes to further reward original content on Instagram: - First, when we find reposted content in recommendations, we will replace it with the original. We'll also add a label to the repost linking back to the original, which will remain visible to the reposter's followers.

Adam Mosseri is the head of Instagram where he oversees all functions of the app including engineering, product and operations.

Each Instagram algorithm ranks content based on different factors: The Instagram Feed algorithm: Your activity in-feed (likes, comments, shares, and saves), and info about the post and the person who posted. The Instagram Stories algorithm: Stories you've viewed or engaged with in the past.
